Fans have so much more information today on minor league players. I routinely watch various parts of minor league games via milb.com. Fifty years ago, The Sporting News would publish dated milb numbers and then Baseball America began in 1981. BA featured fairly complete coverage of prospects and every minor league team, even if it was a bit dated by the time of being published. The progression of coverage has been outstanding for baseball fans.
The Twins have some exciting players worth following in their system. It is also important to remember that experience often defeats youth. There will be roster changes next season, but folks should expect the team to include a number of veterans. I also think the Twins may look to repeat themselves with a trade similar to the Arraez-Lopez deal. There may be a couple of players replaced by less expensive contracts in the utility roles as well. The roster expenditures should be more likely to fall to the $125-140 million range due to a drop in media revenue. I have enjoyed watching the Saints but remember there is a distinct difference between AAA and MLB.
I would be surprised if both Kepler and Polanco are dropped. Buxton has a no trade contract, Correa too. Any discussion/suggestions of trading either are useless. We just don't know what is happening with Byron. We hope he returns fully healthy but perhaps he is reaching a point where he is done physically too. We don't know or at least I don't know. Players that could push for full time infield positions are: Kirilloff, Julien, Lewis, Lee, and Martin with Polanco in the picture and Correa fixed at shortstop. Miranda, Castro, Prato, and Farmer could find utility roles. Castro and Martin fit in the outfield too. I don't expect Lewis on the grass. Thus a trade happens.
